Although the downpour offered respite from the sultry weather, it affected Mumbai's lifeline, the suburban trains network, with local services running late by 10-15 minutes on the Central Railway and the Harbour Line since morning, delaying millions of commuters.

No delays were reported on the Western Railway section.

Air traffic at the Mumbai airport, however, remained largely unaffected. Three flights from Ahmedabad were diverted to Mumbai early today due to inclement weather conditions there, an airport official said.

The city disaster control room said there was no waterlogging in any part of Mumbai.

Commuters travelling by roads, however, reported traffic jams in some parts of the city.

"Due to traffic jams, it took me nearly 45 minutes to cover the distance between Jogeshwari and Vikhroli which normally takes around 10 minutes," said Pagur Desai, who commutes daily from Kandivli-Mulund.
